Aim of the project
Construct an index that measures changes in
animal welfare over time
• Transparent
• Feasible
Copenhagen 27 April 2015
Slide 3
Assessment versus Control
Animal welfare control:
•Minimum level
•All or none
•Mostly risk factors
•No aggregation
•Only ”bad” welfare
Welfare assessment:
•Overall assessment
•Several steps
•Mostly ”here and now”
•Aggregated measure
•Positive welfare

Views on animal welfare
"Pigs should be dirty"
"Happy pigs are dirty"
"General condition"
Our decision
The hedonistic definition
Based on the experiences of the animal
Same definition as Welfare Quality®
Welfare Quality® is used as a reference value

Construction of the national welfare score
Existing data – based on previously available data,
e.g. slaughter data
On farm data – based on on-farm assessments
Final index – a combination of the two
Enhedens navn
Existing data
• Mainly slaughter data
• Selection procedure:
• Welfare relevant
• Comparable between slaughter plants
• Many variables show very large variation
• For some corrections may be used
• Still unclear to what extent slaughter data may
be used

On farm data
Hedonistic definition => should use
animal based measures
Animal based measures often take
longer

The on-farm measures, comparison with WQ®
No social behaviour
No QBA
No human-animal
relationship
New resource based
measures
Few additional animal
based measures
More focus on piglets

Construction of the national welfare score
(similar to WQ)
Measures – e.g. body condition
Criteria – e.g. absence of prolonged hunger
Principles – e.g. good feeding
Overall score for the farm
National score
With the aim of
aggregating
